NAME
asn1_der_decoding_element - Fill the element named ELEMENTNAME of the
structure STRUCTURE with values of a DER encoding string.
SYNOPSIS
#include <libtasn1.h>
asn1_retCode asn1_der_decoding_element(ASN1_TYPE * structure, const
char * elementName, const void * ider, int len, char * errorDescrip-
tion);
ARGUMENTS
ASN1_TYPE * structure
pointer to an ASN1 structure
const char * elementName
name of the element to fill
const void * ider
vector that contains the DER encoding of the whole struc-
ture.
int len number of bytes of *der: der[0]..der[len-1]
char * errorDescription
null-terminated string contains details when an error
occurred.
DESCRIPTION
Fill the element named ELEMENTNAME with values of a DER encoding
string. The sructure must just be created with function string of the
whole STRUCTURE. If an error occurs during the decoding procedure, the
*STRUCTURE is deleted and set equal to ASN1_TYPE_EMPTY.
RETURNS
ASN1_SUCCESS
DER encoding OK.
ASN1_ELEMENT_NOT_FOUND
ELEMENT is ASN1_TYPE_EMPTY or elementName == NULL.
ASN1_TAG_ERROR,ASN1_DER_ERROR: The der encoding doesn't match the
structure STRUCTURE. *ELEMENT deleted.
